What kind of machines can be monitored?
Machines to be monitored by the Easy Check Online should comply with the following requirements:
•
constant rotational speed, constant load, stable operating conditions
•
machines have to be in good condition, suitable for unrestricted long-term operation
according to ISO 10816
Examples of machines that can be monitored:
•
carrying air fan of coal power plant
•
exhauster of a cement mill
•
agitator in a water treatment plant
•
absorber pump for a desulphurisation unit
•
coal mill of a coal power plant
•
recirculation fan of a homogenisation furnace
•
…
To select the exact mounting position please consider the following aspects:
•
mounting position should be as close as possible to the critical parts of the machine
•
allow for good sound propagation
•
stud mounting technique is the first choice
•
vertical positioning should be preferred
•
for mounting the Easy Check Online, the position has to be accessible
•
environmental temperature at max 85°C / 185°F

learning of the ‘good
condition’
BA010-98/122004
The first step is to remove the casing cover to configure
the Easy Check Online.
On the circular board you find the DIP switch and the
Teach in Button (please refer to the photo on the last
page).
The Easy Check Online is delivered with a default setting
for standard machines. This setting can be changed to
adapt the system to monitor a specific machine (please
refer to the table on the last page).
Connecting to the power supply activates the Easy Check
Online.
The reference values of the good condition remain stored
during interruption of power supply. This means no teach in
mode necessary after power interruption.
Preferably screw joint with the lubricating hole:
With the M8 external screw thread the Easy Check Online
can be connected to any M8 tapped hole. The easiest option
is to use the lubricating channel in the bearing housing.
Please take care in sealing the internal M8 screw thread on
top of the Easy Check with a screw plug, lubricating nipple or
the flexible tube of the automatic lubricator (e.g. FAG Motion
Guard) to avoid contamination of the bearing.
Adhesive-bounded joint:
An adaptor is affixed to the machine with a special adhesive.
The Easy Check Online is then screwed onto the adaptor.
Start of the Teach in Mode:
1. Run up the machine and wait until it reaches the regular
operating condition.
2. Press the Teach in Button for about 4 sec – until red,
yellow and green LED flash once.
3. 10 minutes remain to refit the casing cover. Then the
teach in mode starts.
Do not mechanically manipulate the
Easy Check Online any more!
Teach in Mode:
•
yellow and green LEDs flash in turn
•
duration of the teach in mode: about 15 minutes
•
base values (benchmarks) for the good condition are
determined
End of the Teach in Mode:
•
The green LED lights up to indicate the regular monitoring
mode
No new Teach in Mode is needed when:
•
machine is stopped and started again
•
power supply has been interrupted for a while
•
false alarm has been triggered – reset alarm (see 8)
MEASURING
•
compares actual
measurements
with the
’good condition’
Every 16 seconds a new measurement takes place.
The measured values are compared with the base values
and the configured alarm levels (for details please refer to
the examples on the last page).
The LEDs display the actual alarm status.
Blink code of the LEDs:
•
•
•
•
green LED lights up: no alarm – everything is OK
yellow LED lights up: pre-alarm of at least one
measurement value
red LED lights up: main alarm of the acceleration
measurement
red LED lights up + yellow LED flashes: main
alarm of velocity measurement
Other combinations of blink codes are possible depending
on alarm condition.
ALARMS
•
•
exceeding of the
alarm limits
triggers the LEDs
refer to the
blink code
If over a period of about 5 minutes succeeding
measurements exceed the alarm limit, an alarm is triggered.
This way false alarm is excluded.
A main alarm overrules a pre-alarm and only the code with
the red+green or red+yellow combination flashes.
Check the LEDs in regular intervals!
CHECK
•
•
check regularly
more detailed
measurements?
If the Easy Check Online displays an alarm, please check:
• Have the process parameters changed since the teach
in mode?
e.g. load, speed
• Have the mechanical parameters changed?
e.g. reconstructions
• Is the connection of the Easy Check Online still tight?
• Do you need an expert for diagnosis?

SERVICE
•
•
•

BA010-98/122004
After successful service new basic values have to be
determined. Press the Teach in Button again for about 4 sec
until all 3 LEDs flash to start the teach in mode.
Adjust alarm levels: If alarm levels have been set too low
and an alarm is triggered too early, the alarm levels can be
readjusted without a new ‘teach in’. First open casing cover,
then alter DIP switches, press the Teach in Button < 1sec !
to reset the alarms – 10 min remain to refit the casing cover.
Then the regular measuring mode proceeds.
S2.3, S2.4: VELOCITY ALARM SETTINGS
Set the Alarm Levels
The alarm levels are set by the position of the DIP switches which
represent relative values (in % of the base value).
Examples:
Temperature was determined in the teach in mode as 42°C.
•
DIP-switch S1.3 is OFF, S1.4 is ON (pre-alarm +15°C, main
alarm +20°C, see table)
A measured temperature of 57°C triggers a pre-alarm (42°C
+ 15°C), and a measured temperature of 62°C triggers a main
alarm (42°C + 20°C).
Acceleration was determined in the teach in mode as 100mg.
•
DIP-switches S2.3 and S2.4 are both ON (pre-alarm 140%,
main alarm 200%, see table)
With a measured value of 140mg a pre-alarm is triggered,
and with a measured value of 200mg a main alarm is triggered.
